Strangeness with duplicate entries for Apple Magic Trackpad 2

I don’t know if this is just something to focus on with kernel level, but here’s my situation:

I have an Apple Magic Trackpad 2. The settings after suspend and reawaken are always not right, so I habitually unplug and re-plug it when waking my computer. That gets it mostly fine.

When it is recognized, TWO entries for it show in the system settings under touchpad. I can change them independently.

Sometimes everything is consistent. Sometimes, the scroll-direction is backwards for some system things. Like scrolling over the brightness system-tray, up makes the brightness go down — until I turn off inverted scrolling. But inverted scrolling still works when scrolling through web pages and documents.

How can I just have settings working well and persistently?
